I have always hated the admonition to "take all things in moderation." (For one thing, it gets some of its zing from its seeming paradox (Even the tendency to moderate!?), a gimmick that annoys me.) It reminds me of the cosmological principle in astronomy, aka the principle of mediocrity, which is basically that nothing is special and if things start to look like they might be different in one part of the universe than another, you are probably missing something.
